Coupé-like styling is one of the biggest buzzwords at new car launch parties. Although this is more of a modern phenomenon, the root of the seemingly contradictory four-door coupé is older than you might think.

In 1962, Rover dropped the rear roofline on its P5 sedan and dared to call it a four-door coupé. In 2004, Mercedes picked up on this idea with the CLS-class Coupe. It was only a matter of time before Audi and BMW joined the party with the A7 and 6-Series Gran Coupé.

Now, many of you may say we already have a name for the four-door coupé. It’s a sedan. I agree with you. Audi isn’t entirely convinced by the “coupé” designation either, and they only dare mention it twice in the 62-page brochure. This means the S7 is a $12,000 styling exercise atop a tasty and more practical S6.

While it may or may not be the next-generation Mercedes-Benz CLS-class (note:probably not), the automaker took the wraps off a transforming concept car that grows in length significantly at highway speeds to better cut through air.

The Mercedes-Benz IAA concept (Intelligent Aerodynamic Automobile) was shown off Tuesday in Frankfurt and, according to the automaker, can grow by 390 millimeters to achieve a drag coefficient world record of 0.19. (The current generation Prius is around 0.25, for reference.)

The whole thing is powered by a hybrid powertrain that’ll never see the light of day and sports an interior array of electronics that’s probably something out of “Minority Report.” It’s the moveable aerodynamic elements on the IAA that could see production, and there are a lot of them.

With a broader product portfolio and extra decades of established premium status in the United States, Mercedes-Benz USA sells a lot more vehicles than Audi USA. Through the first four months of 2015, Mercedes-Benz sales were up 9% to 107,344, excluding Sprinter. Audi, globally favored, was up 12% to 56,925.

But again, the comparisons are difficult to make because the lineups simply don’t, well, line up. We’ve discussed the CLA and A3 before, but even there, Audi is offering different bodystyles under one banner, which Mercedes-Benz does not. The S-Class has a significantly higher base price than the A8. The E-Class is available as a sedan, wagon, coupe, and convertible – the A6 is sedan only. The GL is significantly pricier than the Q7; the Q7 offers more seats than the ML. The C-Class is new; we might as well wait for a new A4 to draw realistic comparisons. The SLK is a hardtop convertible; the TT is either coupe or convertible.

You get the idea. Only in a handful of zones do the two brands offer truly direct rivals. GLA vs. Q3, GLK vs. Q5, and the matter at hand, Mercedes-Benz CLS vs. Audi A7. (Read More…)

My statement “BMW is the new Mercedes” may have ruffled the most feathers, but the second thing that gets thrown in my face is: “what then has Mercedes become?” I’m sorry if the forum fanboys can’t adjust to the new normal that is a softer, more civilized, more luxurious BMW that puts comfort over balls-out performance. Sometimes you just have to let the ostrich keep its head in the hole. If you think the M6 is the best thing since sliced bread, read no further. This isn’t about BMW, this is about theGerman luxury company. What of them? To find out we were tossed the keys to a six-figure beast for a week.

I appreciate the novelty of a new design as much as the next guy, but have never understood the four-door-coupé. I mean, aren’t these terms mutually exclusive? A coupé can’t have four doors and a car with four doors can’t be a coupé? Mercedes started this conundrum with the CLS back in 2004, and then Volkswagen decided to jump on the bandwagon to bolster Passat sales with the CC in 2008. It was only a matter of time before VAG decided to compete with the CLS head on with the A7. After all, Audi has had model envy for years, and if they are to stay on track with world domination, they need to attack the mainline Germans at every body style. Not one to rest on laurels, Mercedes has redesigned the CLS for 2011. Michael Karesh wrangled an A7 out of Audi back in July, and Mercedes let me take theirs for a week. Let’s see if the CLS has what it takes to reign supreme in this extremely small niche.

Ever since Mercedes lured its competitors into the “four door coupe” segment created by its 2004 CLS, we’ve been waiting for the next fad segment to mangle the definition of the word “coupe” beyond recognition. And here it is: a forthcoming “five-door coupe” that is essentially a wagon version of the CLS. This near-production mule looks remarkably like the concept version, in other words, fantastic. On the other hand, the idea of buying a more-practical version of a less-practical version of an E-Class still doesn’t compute… but then you can’t underestimate the power of fads in the luxury car game. Stand by for competing models from Audi and BMW, not to mention the inevitable six, seven, and eight-door coupes. [via AM unds S]

Thought the idea of a four-door coupe was confusing? How about a five-door coupe? Or, is that a four-door shooting break? While the debate rages on, Mercedes has announced that it will produce a wagon version of its CLS four-door coupe, because, as the video above states

Mercedes is committed to the development of the coupe.

To develop the coupe you must destroy the coupe… or at least the significance of the word “coupe.” By that measure, Mercedes has done quite nicely with this car, and it doesn’t look half bad either. We’re just starting to get a little worried about where all this coupe “development” is going to end up.

With the debut of Audi’s A7 Sportback, and a BMW four-door GranCoupe coming in 2012, it’s clear that the four-door coupe segment is here to stay. At least in Europe. This year Mercedes is coming back into the segment swinging, with an updated CLS shown here in the first leaked official images [via Autocar]. But will the four-door coupes ever make serious headway in the US market? In the last 12 months, the CLS has sold fewer than 2,000 examples in the US market. VW’s Passat CC on the other hand has sold 29,114 units in the last 12 months, more than double the volume of the regular Passat. What does this say about four-door coupes in the US market? Probably that their sales depend heavily on the appeal of their sedan versions: Mercedes sedans have become handsome enough to make the CLS look overstyled, while the CC offers much-needed visual flair to the otherwise-anodyne Passat. But will the segment grow as BMW and Audi wade in?

With Audi’s A7 four-door coupe making waves at its release yesterday, the segment-defining Mercedes CLS just had to remind the world that its successor is on the way. Accordingly, these photos of the 2012 CLS have hit Autoexpress, granting the internet its first look at the redesigned not-quite-coupe. And though there’s definitely some Audi-inspired headlight gizmology going on with the new CLS, the overall design doesn’t seem to pop quite as dramatically as the A7. Perhaps it’s because the E-Class is already a quite handsome sedan (especially by recent M-B standards), or maybe Mercedes is saving the visual drama for a planned five-door coupe-wagon version. Either way, it’s difficult to see the CLS dominating the segment it invented going forward.

Having a hard time understanding the stream of inexplicable niche products coming out of the German automakers recently? Mercedes isn’t about to make things any easier. According to the latest print edition of Auto Motor und Sport, Mercedes has fallen so far down the segment-busting rabbit hole, it’s planning a “Shooting Brake” wagon version of its already-confusing four-door coupe, the CLS. Intended, of course, to compete with the BMW 5GT and Audi A7. Look for a concept inspired by this 2008 ConceptFascination study to debut at this fall’s Paris Auto Show. Then expect Audi and BMW’s designers to drop even more acid and talk their bosses into producing a landaulet-roofed, seven-door, MPV-coupe. You know, just to see if Mercedes makes one too.
